CUFF BUTTON.

Application filed May 12, 1922. Serial No. 560,428.

T 0 all whom it may concern.

Be it known that I, BERNARD GoLnsTEiN, a subject of the King of GreatBritain, and resident of the city of Toronto, county of York Province ofOntario, in the Dominion of Canada, have invented certain new and usefulImprovements in Cuff Buttons, described in the following specificationand illustrated in the accompanying drawings, that form part of thesame.

The principal objects of the invention are, to avoid the inconvenienceand unpleasant conditions caused by the accidental separatin of thebutton members and to provide a liutton which will lock securely when ina closed position but which may be separated very easily.

A further object is to devise a two piecebutton which may be used withstiff cuifs without undue restriction and injury to the cuff.

A still further object is to devise a structure which may be easilymanufactured and assembled.

The principal feature of the invention consists in the novelconstruction and arrangement of parts, whereby the connecting shank islocked in the socket portions of the buttons by spring members adaptedto enter between the inner wall of the socket andreduced neck portionsof the shank and whereby one of said locking members may be withdrawnfrom the locking position to release the shank.

In the drawings, Figure 1 is an enlarged sectional View of a buttonconstructed according to this invention showing the members in thelocked position.

Figure 2 is an enlarged sectional view showing the button membersseparated.

Figure 3 is an enlarged perspectiile detail of the spring locking memberseparated from the button.

Figure t is an enlarged elevational View of a button provided with'abent shank.

Figure 5 is a view similar to Figure 4 showing a flexible shank.

The separable button type of cufl button has been brought intoconsiderable use but with the types having a snap spring grip thesprings do not hold satisfactorily and the buttons come apartaccidentally and very often cause considerable inconvenience and it isthe purpose of this invention to definitely and automatically lock thetwo members together so that they cannot be pulled apart by theapplication of force but may be very easily separated by properlyreleasing the same.

The button members are here shown each formed with a conveXed crownplate 1 and spun body portion 2 converging from the crown plate andforming the narrow throat 3 and then diverging to form a flaring mouth4:.

One of the buttons is provided with a convexed spring plate 5 looselyheldbetween the body and the crown plate. The locking member 6. which isof sheet metal, is formed with a plurality of convergent fingers 7curved longitudinally to conform to the converging contour of the body 2and having the tips curved transversely to conform to the crosssectional curvature of the body adjacent to the throat 3. This member isheld into the throat by the spring plate 5.

i A locking member 8 similar to the member 6 is arranged in the otherbutton and attached to this locking member is a shank 9 which extendsthrough the crown plate anal has a small knob 10 secured on its outer enAn arched spring 11 is arranged upon the shank 9 and the ends thereofbear against the crown plate and hold the locking member into the throatof the button but by pulling upon the knob 10 this locking member may bewithdrawn from the throat of the button.

The shank 12 is formed with the head ends 13 each having aconvergingneck portion 14. These head ends are adapted to enter into ihethroat openings 3 of the button memers.

The maximum diameter of the heads is slightly smaller than the throatopenings 3 so that they will enter freely and the neck portions conformin contour to the shape of the inner surfaces of the fingers of thelocking members.

he fingers of the locking members are adapted to spread apart to receivethe head of the shank 12 and then fit snugly around the neck ortionthereof and between said neck portion and the interior of the throat 3.

The shank is assembled as part of the button containing the spring plate5 by being pushed into the'throat. The head end pushes the lockingmember inward flexing the plate 5, and spreading the fingers 7 itslipsin between them and the spring plate 5 pushes the locking memberoutwardly so that the locked in the button.

In the form shown in Figure 4 the shank 15 is curved to hold the buttonsat an angle the one to the other and conforming to the natural angle ofa stifi cuff. The cuff is not drawn in too close as is the case with theordinary button. In Figure 5 the shank 16 is shown with a link or swiveljoint to allow the buttons to assume the angle of the cuff.

In the use of this button when the members are separated the archedspring 11 holds the locking member 8 to its outward position so that itsspring fingers engage the throat of the tapered body portion 2. When thebuttons are pressed together the head of the stud engages the ends ofthe fingers. The locking member is pushed inwardly against the tensionof the spring 11, as shown in Figure 2, until the pressure overcomes theinward tension of the spring fingers, said fingers then spread apart andallow the head of the stud to enter further. As the head moves inwardlyassuming the position shown in Figure 1 the locking fingers slip overthe head and enter between it and the wall of the body portion. When inthis posit-ion the fingers engage the body portion on the outer side andthey thus form a liner within the neck of a smaller diameter than thehead which thus effectively prevents the removal of the head from thebody and the two buttons are locked securely together and will tear topieces beforathey will separate.

When it is desired to separate the buttons the knob 10 is pulledoutwardly thus drawing the fingers of the locking member inwardly fromtheir locking position surrounding the head of the shank and the shankis then free to be withdrawn.

It will be seen that a button such as described will hold very securelyand will be absolutely dependable and is capable of bein very easily andquickly disengaged.

Vhat I claim as my invention is 1. A cufl button, comprising, a pair ofsocket members each havin a convergent throat, a shank having hea endsand reduced neck portions, a locking member arranged in one socketmember and adapted'to encircle the neck of the shank and permanentlyprevent withdrawal of the head, a

locking member arranged in the other socket adapted to encircle the neckof the shank to hold it securely from withdrawal, and means arranged inthe latter socket member for withdrawing the locking member to releasethe shank and means for effecting the withdrawal of one of the lockingmembers.

2. A cufl' button, comprising, a pair of socket members each having aconvergent throat, a shank having reduced neck portions, a lockingmember arranged in each socket member and having a plurality of springfingers adapted to surround the head and embrace the neck of the shankwithin the throat of the socket member, and spring means adapted to movesaid locking member into the throat on the insertion of the headthereinto. v

3. A cufl' button, comprising, a pair of socket members each having aconvergent throat, a slidable member extending through a, hole in thecrown of one socket member and having a knob on its outer end, a memberhaving a plurality of curved spring fingers secured at the inner end ofsaid slidable member, a shank irremovably secured in the other socketmember and having a head adapted to be engaged by said spring fingersand locked in place, and a spring member arranged to hold said slidablemember inwardly.

4. In a cuff button, a Socket member having a convergent throat,alocking member arranged within said button and having a plurality ofspring fingers extendinginto the throat, a spring member arranged tohold the fingers of said locking member in the throat, and a shankmember provided with a head adapted to enter the throat and a neck toreceive the spring fingers of the locking member.
